Yes, the soft was expecially for that boost. And the temps around were +28C, so the amount of good air was not excessively high for the fuel supplied...

When you realised one of the cylinders on your VT3 (no 4) was lower than the rest, why didnt you stop driving it and sort that out first? did you change the pully on the VT3 as well after it was built?

VT3 system of pulleys is totally new and not somehow similar to VT2. After the compression was measured at being 8.8 in 4 th cylinder and all the things were changed the car was runnning clean, prior to that pull. How is it possible to sort that problem is the compression is already 8.8???? That should have not been like that anyway fron the very beginning.

I really do hope you get something sorted as it sound like a lot of money you have spent and what should be an enjoyable time is a nightmate.
